The nomenclature used for the different graph models is:

'building-'+eta+'-'+rep'+extension

Being:
* eta: the number of STAs per AP. eta ranges from 1 to 12.
* rep: the number of repetition. rep ranges from 1 to 10, i.e., for each value of eta we provide 10 different graphs.
* extension: for an easier use, we provide different formats for the graph: '.pk' (pickle, preferred format), '.gml' and 'gml.gz' (compressed gml).

For each graph we also provide a number of representations:
* A 3D representation.
* A cut of the 3D representation over the three dimensions.
